I have a calculator, specially the Casio fx-9750GII,but there is a "slight" error...

When I put in, for example cos (76

I get the answer in radians.

So, naturally as anyone that's not lazy would do I converted to degrees (instead of buying a new one :] ) and I got the right answer, but everyone gets lazy sometimes, and I was wondering how to just set the calculator to degrees, if that is possible?

Thanks in advance!

    $\begingroup$ This is not a mathematics question. Most calculators that I know have a button to switch between degrees and radians. If not, get used to multiplying by $\frac \pi{180}$. And note, the answer is not in degrees or radians, the input is. $\endgroup$ Jun 3 '19 at 19:32
  • $\begingroup$ @RossMillikan Alright, thanks! Where should I put this question instead? $\endgroup$ Jun 3 '19 at 19:33
  • $\begingroup$ Try searching for "Casio fx-9750GII degree mode" first. $\endgroup$

  • $\begingroup$ @copper.hat I actually figured it out! Check out my answer but thanks for the help! $\endgroup$ Jun 3 '19 at 19:36

Try resetting you calculator

Shift 9 (CLEAR) then press 1 to clear setup

hopefully this will default to degrees


Simply press : SHIFT Mode (next to ON key) Then choose '3' for Degrees

BUT I just checked out your calculator online and I think it is different from mine

I think for yours, press SHIFT MENU for the SET UP and then choose Degrees?

hope this helps!

  • $\begingroup$ Hah no, I just searched up your calculator version and figured myself too $\endgroup$

I'm sure yt.'s answer works on most calculators, but on the Casio fx-9750GII you need to click shift then menu then scroll down to angle and click f1

Hopes this helps!
